Which graph can be used to find the solution(s) to x2 – 1 = x + 1?




Let
[tex]f(x)=x^{2}-1[/tex]
[tex]g(x)=x+1[/tex]
we know that
The function f(x) is a vertical parabola open upward
the vertex is the point [tex](0,-1)[/tex] ------> is a minimum
The function g(x) is a linear equation
The y-intercept is the point [tex](0,1)[/tex] -----> for [tex]x=0[/tex] find the value of g(x)
therefore
the answer in the attached figure
The graph that can be used to find the solution of the given polynomial is given by option C) and this can be determined by using the given data.
Given :
Equation --- [tex]x^2 -1 = x+1[/tex]
The following steps can be used in order to determine the graph that can be used to find the solution of the given polynomial:
Step 1 - Separate LHS and RHS of the given polynomial.
[tex]\rm y = x^2-1[/tex] --- (1)
y = x + 1 --- (2)
Step 2 - Draw the graph of a line (y = x + 1) that passes through the points (-1,0) and (0,1).
Step 3 - Now, draw the graph of the equation (1). The shape of this graph is the upward parabola.
Step 4 - The two graphs intersect each other at (-1,0) and (2,3).
From the above steps, it can be concluded that the correct option is C).
